The separability of consumer desires is a necessary and sufficient condition for multi-stage budgeting and Collectivization is consistent of commodity where costs are allocated between edible groups using price indices and intergroup allocations are made independently of other groups. Given the high share of Citrus fruits, Cucurbits and vegetables types (29/5% percent of household food and beve...

introduction: agriculture as one of old sectors of economy has been important role in the supply food for peoples and raw materials. globalization causes rapid growth of world trade and reduces information and communications costs. globalization and rapid growth of trade increases the potential benefits of trade for agriculture from various aspects. the potential benefits of trade for agricultu...

We estimate the price elasticity of residential district heating demand in Denmark using Blundell–Bond two-step generalized method moments (GMM) estimator and a sample 152,913 observations covering period 2015 to 2019. Moreover, we analyze heterogeneity response increases among various household groups investigate distributional consequences policies that increase heating. To this end, measure ...

We introduce a measure of elasticity of stochastic demand, called the elasticity of the lost-sales rate, which offers a unifying perspective on the well-known newsvendor with pricing problem. This new concept provides a framework to characterize structural results for coordinated and uncoordinated pricing and inventory strategies. Concavity and submodularity of the profit function, as well as s...

iran has experienced high food prices in recent years. this paper examines the welfare impacts of rising major food groups' prices on iranian urban households using quadratic almost ideal demand system (quaids) approach. the elasticity coefficients derived from quaids are used to estimate compensated variations (cv).the study uses iranian household expenditure and income survey (heis) raw data,...

In this journal, Seldon (1986) recently criticized the arc elasticity concept as it is commonly taught in the principles course. In doing so, he resurrected the Lerner (1933a) measure of elasticity, which is based upon the lower values of price and quantity in a price change rather than the average values used in the traditional measure (i.e., the midpoint formula). Seldon argued that the Lerne...

A retailer following a competition-based dynamic pricing strategy tracks competitors' price changes and then must answer the following questions: (1) Should the retailer respond? (2) If so, respond to whom? (3) How much of a response? (4) And on which products? The answers require unbiased measures of price elasticity as well as accurate knowledge of competitor significance and the extent to wh...

Policymakers in countries around the world are faced with rising health care costs and are debating ways to reform health care to reduce expenditures. Estimates of price elasticity of expenditure are a key component for predicting expenditures under alternative policies. Using unique individual-level data compiled from administrative records from the Chilean private health insurance market, I e...

Abstract: On December 2010, the government of Iran ended the decades-long subsidy program for bread and energy products and launched the Targeted Subsidy Reform program that considerably raised prices of food products. The objective of the study was to measure welfare impacts of food price changes on Iranian urban households between two survey data of 2009/10 and 2011/12 which were taken from I...
